This is such a great recipe to prepare for company. It is ultra rich so it will feed a ton of people. Especially if you serve it with a green salad and garlic bread.

Creamy, Cheesy Texture

A combination of cream cheese, cottage cheese, and sour cream and a jar of alfredo sauce makes one super creamy and rich casserole. In addition to all the creaminess, there’s 4 types of cheese on top. Provolone cheese, mozzarella cheese, cheddar and Parmesan.

Tips For Making Million Dollar Chicken Alfredo

I prefer using rotisserie chicken for this recipe. Not only is it super convenient, rottiserie chickens are well-seasoned and moist and hold up well in a casserole.
Be sure not to overcook the pasta. If anything, you want to slightly undercook it. It will cook more in the oven.

I’ve used fettuccine, but you could use spaghetti, penne, cavatappi, or linguine..
You can make this casserole vegetarian by substituting the chicken with steamed broccoli.
This casserole can be assembled up to 8 hours ahead of time and refrigerated. Try to leave it at room temperature for 30 minutes before baking or add a few minutes to the bake time.
